Abstract : Midship bending stress and environmental data from four dry-cargo ships, accumulated during the period 1959 through early 1970 under Ship Structure Committee Project SR-153, Ship Response Statistics, have been processed and written on digital magnetic tapes. During the processing, selected statistical information was derived which has been included on the digital tapes for each of the 13220 intervals recorded. The original FM analog data were contained on 163 reels of magnetic tape. The entire collection is now stored on 25 reels of digital tape and tape and pertinent reduced data from each interval are stored on two summary reels. Processor programs were written to convert the original analog data and environmental information to the final digital format and to provide a capability to extract portions of the data for subsequent statistical analysis.
